P28.13: Comparison between sonovaginography and nuclear magnetic resonance in the diagnosis of posterior deep infiltrating endometriosis

A prospective study to compare sonovaginography and nuclear magnetic resonance in the diagnosis of posterior deep pelvic endometriosis. All women underwent sonovaginography and nuclear magnetic resonance. Laparoscopic surgery and histological diagnosis was performed in all women. Sonovaginography presented higher accuracy respect the other procedures being also more comfortable for the patient than transvaginal ultrasound. Nuclear magnetic resonance and even sonovaginography were more accurate in diagnosing and discriminating the different localizations of endometriotic lesions. In the diagnosis of rectal infiltration, we found mean values of sensibility, 66.7% for both the two techniques and specificity of 93.8% and 95.8%, for sonovaginography and nuclear magnetic resonance, respectively. Sonovaginography should be used in the diagnosis of deep pelvic endometriosis.
